Microbial extracellular vesicles contribute to antimicrobial resistance

Area of Science:

• Microbiology
• Molecular Biology
• Drug Discovery

Background:

• The global antimicrobial resistance crisis necessitates novel therapeutic strategies.
• Microbial extracellular vesicles (EVs) are increasingly recognized as significant contributors to antimicrobial resistance.
• Existing knowledge on the precise mechanisms of EV-mediated resistance across different microbial types is fragmented.

Purpose of the Study:

• To systematically review and synthesize current research on the role of microbial EVs in antimicrobial resistance.
• To elucidate the diverse mechanisms by which bacterial, fungal, and parasitic EVs promote resistance.
• To explore the potential of bacterial EVs as a therapeutic approach against drug-resistant microbes.

Main Methods:

• Systematic literature review of studies investigating microbial EVs and antimicrobial resistance.
• Analysis of mechanisms of resistance conferred by bacterial, fungal, and parasitic EVs.
• Evaluation of current and potential applications of bacterial EVs in antimicrobial therapy.

Main Results:

• Microbial EVs actively contribute to antimicrobial resistance through various mechanisms, including horizontal gene transfer and modulation of host immune responses.
• Bacterial, fungal, and parasitic EVs exhibit distinct yet overlapping strategies in promoting resistance.
• Bacterial EVs show promise for development into novel antimicrobial agents.

Conclusions:

• Elucidating the multifaceted roles of microbial EVs in resistance is crucial for developing effective countermeasures.
• Targeting EV-mediated resistance mechanisms offers a promising avenue for combating drug-resistant pathogens.
• Bacterial EV-based therapies represent a potential innovative strategy in the fight against antimicrobial resistance.
